True, but i figured trimming a little off the catch was easier than trying to find perfect thickness shims, where you run the risk of one being too thick and the mag being loose, or another being too thin and still having to trim the catch.
Also, looking at genuine steel AICS mags, I'm thinking I would not have had the interference issue, as they look like the lips stop long before the bumps in the receiver.
